Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */
This contains a few small fixes for this merge window:

* Fix io_uring based write-through after converting cifs to use the netfs
  library.
* Fix aio error handling when doing write-through via netfs library.
* Fix performance regression in iomap when used with non-large folio mappings.
* Fix signalfd error code.
* Remove obsolete comment in signalfd code.
* Fix async request indication in netfs_perform_write() by raising BDP_ASYNC
  when IOCB_NOWAIT is set.
* Yield swap device immediately to prevent spurious EBUSY errors.
* Don't cross a .backup mountpoint from backup volumes in afs to avoid infinite
  loops.
* Fix a race between umount and async request completion in 9p after 9p was
  converted to use the netfs library.
